Special one: Cristiano Ronaldo receives congratulations for his birthday from the fans

But Ronaldo's special day was slightly soured when he was taunted with chants of 'Messi, Messi' - in support of Barcelona rival Lionel Messi - as he signed autographs for fans in Portugal after arriving in the country for Wednesday's friendly against Ecuador.

Also celebrating today are former England
and Manchester City manager Sven Goran Eriksson, ex-Scotland
striker Billy Dodds, former Arsenal and Rangers midfielder Giovanni van
Bronckhorst, ex-Australia centre forward John Aloisi and Vedran
Corluka, the Lokomotiv Moscow and Croatia defender who used to play for Manchester City and Tottenham.
